During an accidental release of tritium, mechanisms of hydrogen transferfrom air to man are very numerous, dependent on multiple climate,physiological and biological parameters, and the kinetic is highlyvariable from one environmental compartment to another. To evaluatethe impact of an acute tritium release requires either an overallassessment of the state of the environment during the release and thefollowing hours from a number of restricted data, or the establishmentof a significant data bank, a complex model and a system of dataacquisition in real time whose potential for daily purposes is veryhypothetical. To facilitate the first approach, this paper discussesthe key elements of the mechanisms to guide the choice of parametersfor a rapid assessment of the situation, and to clarify the typesof measurements to carry out and their interpretation.
